I saw a topic about music in the off-topic section. But why not one in general gaming discussion about game music! And by that I mean music created for games, not music in games.
What I really love about music from games is that it can bring back a nostalgia feeling much stronger then most other music can do for me. I think this is cause the music was always connected to the game while other music is often connected to many moments in life.

The music in Doom is still one of the best, and I think almost everyone here knows this music.
